Claim 5

The apparatus of claim 1 wherein each of said lifting eye means comprises: a cylindrical socket providing an open end and terminating at an inner stop; a plate affixed rigidly to said socket and extending downwardly and rearwardly from said open end of said socket;

Claim 6

at least one opening in said plate receptive of lifting lines; and gusset means on said plate for stiffening said plate.

Claim 7

at least one opening in said plate receptive of lifting lines; and gusset means on said plate for stiffening said plate.

Claim 8

A spreader bar assembly comprising: a. a rigid elongated support bar; b. a pair of lifting eye means removably connected during a lifting operation at each respective end portion of the bar for forming a connection with an above supporting bridle line and at least one depending lift line, each of said lifting eye means comprising: a cylindrical socket providing an open end and terminating at an inner stop; a plate affixed rigidly to the socket and extending downwardly and rearwardly from the open end of the socket; at least one opening in the plate receptive of lifting lines; and gusset means on the plate for stiffening the plate, the gusset means comprising a vertical gusset affixed rigidly to the plate at an angle thereto, the cylindrical socket at substantially right angles to the longitudinal axis thereof, and a horizontal gusset affixed rigidly to the plate at an angle thereto, the horizontal gusset being affixed in part to the socket.

Claim 9

A spreader bar assembly comprising: a. a rigid elongated support bar; b. a pair of lifting eye means removably connected during a lifting operation at each respective end portion of the bar for forming a connection with an above supporting bridle line and at least one depending lift line, each of said lifting eye means comprising: a cylindrical socket providing an open end and terminating at an inner stop; a plate affixed rigidly to the socket and extending downwardly and rearwardly from the open end of the socket; at least one opening in the plate receptive of lifting lines; and gusset means on the plate for stiffening the plate, the gusset means comprising a vertical gusset affixed rigidly to the plate at an angle thereto, the cylindrical socket at substantially right angles to the longitudinal axis thereof, and a horizontal gusset affixed rigidly to the plate at an angle thereto, the horizontal gusset being affixed in part to the socket.

Claim 10

The apparatus of claim 5 wherein said socket provides a cylindrical side wall to which said horizontal gusset is tangently attached.

Claim 11

A spreader bar assembly for use with a bridled load line comprising: a. an elongated integral bar of generally uniform cross-section at its ends; b. a pair of lifting eye assemblies connected during a lifting operation to each respective end portion of the bar and forming a connection therewith, each of the lifting eye assemblies comprising: a female socket providing an open end bore of uniform section and terminating at an inner stop plate transversely affixed to the inner portion of the bore, the female socket normally occupying a position abutting the end portion of the elongated support bar; reinforcing means positioned on the opposite side of the stop plate from the open end bore for strengthening the ability of the stop plate to carry loads transmitted thereto from the bar; an eyelet plate integral with the socket and extending downwardly and rearwardly from the open end portion of said socket; at least one eyelet opening in the eyelet plate for connecting the bridle line to the eyelet plate.

Claim 12

A spreader bar assembly for use with a bridled load line comprising: a. an elongated integral bar of generally uniform cross-section at its ends; b. a pair of lifting eye assemblies connected during a lifting operation to each respective end portion of the bar and forming a connection therewith, each of the lifting eye assemblies comprising: a female socket providing an open end bore of uniform section and terminating at an inner stop plate transversely affixed to the inner portion of the bore, the female socket normally occupying a position abutting the end portion of the elongated support bar; reinforcing means positioned on the opposite side of the stop plate from the open end bore for strengthening the ability of the stop plate to carry loads transmitted thereto from the bar; an eyelet plate integral with the socket and extending downwardly and rearwardly from the open end portion of said socket; at least one eyelet opening in the eyelet plate for connecting the bridle line to the eyelet plate.

Claim 13

The apparatus of claim 7 wherein the socket is cylindrical and provides a uniform internal cylindrical bore and said reinforcing means comprises a sleeve in the socket.

Claim 14

The apparatus of claim 8 wherein said reinforcement sleeve is of a corresponding section to the elongated bar.

Claim 15

The apparatus of claim 7 wherein each of said lifting eye assemblies provides a pair of spaced apart lift eyelet openings.

Claim 16

The apparatus of claim 10 wherein said pair of openings are generally vertically aligned.

Claim 17

The apparatus of claim 7 wherein said elongated bar is of uniform cylindrical cross section.

Claim 18

The apparatus of claim 12 wherein the socket is of uniform cylindrical cross section and of an internal diameter substantially equal to the outer diameter of the elongated bar.

Claim 19

The apparatus of claim 7 wherein the eyelet plate is generally coplanar with the axis of said elongated bar.

Claim 20

The apparatus of claim 7 further comprising a plurality of gussets transversely affixed to said eyelet plate and connecting structurally to said socket.

Claim 21

The apparatus of claim 7 wherein said elongated bar is a single integral structural member.

Claim 22

The apparatus of claim 16 wherein said elongated bar is cylindrical and each of the sockets provides a cylindrical recess correspondingly sized to receive an end of said bar thereinto.

Claim 23

The apparatus of claim 8 wherein there are a pair of lift openings in the eyelet plate and there is a further provided a multi plate thickened portion of the eyelet plate about each of the openings.
